Constantine enacted another change that helped accelerate the fall of the Roman Empire. In 330 C.E., he split the empire into two parts: the western half centered in Rome and the eastern half centered in Constantinople, a city he named after himself.
The city of Rome was taken over several times by barbarians, notably in 410 AD when the Goths sacked the city . The last Western Roman emperor, Romulus Augustus, resigned in 476 AD. The Roman Empire would last another 1,000 years as the Byzantine Empire in the east. The main coin of the Roman Empire was the silver denarius.
